Nests in wet, grassy meadows (Conover 1926, Brandt 1943). On the Seward Peninsula, breeds in wet meadows located on extensive flats with freshwater ponds (Kessel 1989). In the Pitmegea River region (northwest AK), breed in sedge willow, wet meadow or sedge marsh along drainages near ponds (Childs 1969).
In the northwestern foothills of the Brooks Range, this species is restricted to Carex marshes near upland lakes and river bends (Maher 1959) and in the Y-K Delta, breeds in moist upland freshwater meadows (Brandt 1943).
